JOINTEC GRM modular structural joints in metal and rubber
JOINTEC GRM aluminum structural expansion joints are composed of twin metal profiles that allow rotational movement between the metal flanges and the central synthetic rubber insert. Designed to bear loads of large scale buildings or building compounds, they can be installed in the interstitial space between two sections of a building or between two bays. This technical joint links these interspaces, moving three-dimensionally to accommodate a building’s structural and material settlement. The structural bays defined by this profile should be further subdivided with smaller scale movement / expansion joints, chosen according to the expected use and flooring type.
How to install joints JOINTECGRM
INSTALLATION: • Slide the central metal insert into the side flanges. • Snap the synthetic rubber insert into the profile before aligning and positioning the expansion joint on site. • If necessary, protect the rubber insert with masking tape. • Anchor the side flanges with appropriate screws, 11-13/16’’ (30cm) on center, on both sides of the profile. • Lay mortar bed over the side flanges, and install the tiles as normal.
